After a BCS recovery, some entries in the recovered BCS might not accurately reflect the current characteristics of a data set or VSAM object. The VVDS, VTOC, and tape labels should contain the accurate information for existing data sets. Data sets can only be recataloged into the catalog specified in the VVR/NVR unless they are pagespace, swapspace or SYS1 data sets.

For SMS-managed data sets and all VSAM data sets and associations, BCS entries can be recataloged using the access method services DEFINE command with the RECATALOG option. If there is a BCS entry for the data set, first remove it using DELETE NOSCRATCH.

For non-VSAM, non-SMS-managed data sets, you can delete the BCS entry using the DELETE NOSCRATCH command. Then, you can catalog the data set with DEFINE NONVSAM. If the BCS entry for the data set is missing, you can use DEFINE NONVSAM without first using DELETE. For information on DEFINE NONVSAM, see z/OS DFSMS Access Method Services Commands.

To recatalog a data set or VSAM object using the DEFINE RECATALOG command, the corresponding entries in the VVDS and VTOC must exist. This information is used to rebuild the BCS entries, along with information supplied in the command. Data sets can only be recataloged into the catalog specified in the VVR/NVR unless they are pagespace, swapspace or SYS1 data sets.

You might also need to recatalog a data set or VSAM object if you used DELETE with the NOSCRATCH option to delete a BCS entry, or if you restored a volume.

To successfully recatalog a data set or VSAM object, you generally must supply the entry's name, volume, and any ownership, protection, or expiration attributes defined for the entry. Occasionally, you might need to specify the space attribute, and the data set organization. When recataloging alternate indexes, you must also specify the object to which the index is related.

When recataloging VSAM data sets, do not specify component names. They are obtained from the VVDS.

If the data set or VSAM object is protected by a discrete RACF® profile, it must be recataloged with that profile. This information is kept in the VTOC or VVDS.
